￭ DC switch/disconnector
The DC switch/disconnector [Q11] is optional (F286). The DC switch/disconnector
has an operating handle on the cabinet door. A converter unit with a DC switch/disconnector
also has a charging circuit including a charging switch on the door.
The DC switch/disconnector allows the isolation of the unit from the DC bus. Before the unit
is connected to the DC bus, the capacitors of the converter modules must be charged
through a charging circuit.
￭ Charging switch
A converter unit with a DC switch/disconnector ([Q11], F286) also has a charging
circuit and a charging switch [Q10] on the cubicle door. Before closing the DC
switch/disconnector, close the charging switch. After the precharging is finished, the Charging
OK indicator [P11] (green) on the cabinet door illuminates, and you can close the DC
switch/disconnector [Q11], and open the charging switch.
￭ Door lights
The load disconnected indicator ([P13], white) is always installed on the cabinet door. This
indicator shows the state of the energy storage disconnecting device (user-defined).
The charging OK indicator ([P11], green) and DC/DC converter disconnected indicator
([P12], white) are installed when the converter has the DC switch/disconnector (option
+F286).
